[fpc-pascal] arm-linux, program does not start when using unit pthreads

[Bernd Mueller]

Hello,

when I try to start a simple "Hello"-Program, which uses the unit 
pthreads, on an arm-linux target (uClibc), I get the message "not 
found". The program is crosscompiled from win32, using the fpc 2.2.0 
compiler:

program project1;
{$mode objfpc}{$H+}
uses pthreads;

begin
    Writeln('Hello');
end.

There seems to be a problem with the shared libraries. I checked the 
directory /lib for the libraries and symlinks, but the required 
libraries seem to be present.

ldd project1
checking sub-depends for '/lib/libpthread.so.0'
checking sub-depends for '/lib/libc.so.0'
	libpthread.so.0 => /lib/libpthread.so.0 (0x00000000)
	libc.so.0 => /lib/libc.so.0 (0x00000000)
	/lib/ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x00000000)

Then I compiled a gcc "Hello"-program with the library pthread linked 
in. This program runs fine. This is the ldd output:

ldd p
	libpthread.so.0 => /lib/libpthread.so.0 (0x4000e000)
	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40028000)
	libc.so.0 => /lib/libc.so.0 (0x40038000)
	ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)

I am also wondering about the differences in the address fields of the 
ldd ouput. All fpc address fields are set to 0x00000000, while the gcc 
address fields have different values.

Thank you for any hints and pointers.

Regards, Bernd.
